Frequently asked questions
What is the lug width of the Oris Big Crown 01 754 7749 4365-07 5 17 66G?
The lug width is 17mm. This measurement refers to the distance between the watch case's attachment lugs and determines compatibility with all aftermarket straps. It should be measured perpendicularly to the watch's longitudinal axis using a digital calliper.
What is the best strap for the Oris Big Crown 01 754 7749 4365-07 5 17 66G?
A vegetable-tanned calf leather strap in cognac or dark brown amplifies the warmth of the patinised bronze case. Alternatively, alligator leather with visible grain adds tactile presence. For a sporty aesthetic, a heavy cotton NATO or FKM rubber strap provides daily versatility whilst maintaining visual proportion with the 38mm case.
How do I change the strap on the Big Crown 01 754 7749 4365-07 5 17 66G?
Remove the watch from your wrist and place it on a soft surface (cotton cloth). Locate the attachment lug on one side, insert a spring bar tool beneath the lug towards the pin, gently compress the internal spring to release the pin. Repeat on the opposite side. Align the new 17mm strap's keepers to the lugs and compress the spring until it locks into position.
Can I use a non-Oris aftermarket strap on this watch?
Yes, provided the lug width is exactly 17mm. Ensure the strap's keepers are wide enough to accommodate the attachment pin (typically 1.8–2mm diameter) and that the buckle or closure system (deployante, standard buckle, or NATO) is proportionate to the case dimensions.
How long does a leather strap last on this watch?
A vegetable-tanned calf strap worn daily lasts 18–36 months before replacement is warranted, depending on moisture and perspiration exposure. The leather will develop natural patina and may darken. An FKM rubber strap maintains elasticity for 3–5 years with minimal maintenance. A heavy cotton NATO strap is virtually indefinite, as fabric does not degrade like leather.
